Embryonic stem cell-based technology to study gene function in the mouse.
Written in English
Mouse embryonic stem (ES) cells have revolutionized gene function studies in the mouse. Manipulation of the ES cell genome and in vitro screening allow for generation of precisely engineered genomic alterations including control of transgene integration position and copy number. Improvement of ES cell technology is the focus of the following work. A mouse line expressing Cre recombinase in a neuron-specific manner was established by placing Cre under the control of the endogenous tau locus. Characterization of this mouse line revealed that tissue-specific reporter expression is achieved; however, this mouse line should be used with caution. A novel site-specific integrase called &phis;C31 was added to the toolbox of site-specific recombinases. Extensive characterization of the system revealed that high integrase expression level is important for recombination. The results suggest a mechanism for &phis;C31 function and a new approach to make &phis;C31 integrase a useful tool to study gene function in mouse.

Stem-cell therapy is the use of stem cells to treat or prevent a disease or condition. As of , the only established therapy using stem cells is hematopoietic stem cell transplantation (HSCT). This usually takes the form of a bone marrow transplantation, but the cells can also be derived from umbilical cord ch is underway to develop various sources for stem cells as . Induced pluripotent stem cells (also known as iPS cells or iPSCs) are a type of pluripotent stem cell that can be generated directly from adult cells. The iPSC technology was pioneered by Shinya Yamanaka’s lab in Kyoto, Japan, who showed in that the introduction of four specific genes encoding transcription factors could convert adult cells into pluripotent stem cells.
Embryonal stem cells. In the early sixties researchers isolated a single cell type from a teratocarcinoma, a tumour derived from a germ cell. These embryonal carcinoma cells are the stem cells of teratocarcinomas which can be considered the malignant counterparts of embryonic stem cells that originate from the inner cell mass of a blastocyst stage by: Ménard C et al () Transplantation of cardiac-committed mouse embryonic stem cells to infarcted sheep myocardium: a preclinical study.

p38 MAP kinase α (p38α) regulates various cellular processes in adult cells, but little is known about its function in stem cells. We investigated the potential of wild type and p38α deficient mouse embryonic stem cells (ESCs) to differentiate into endothelial cells (ECs), smooth muscle cells (SMCs), and by: Unraveling the mechanisms underlying early neural differentiation of embryonic stem cells (ESCs) is crucial to developing cell-based therapies of neurodegenerative diseases. Neural fate acquisition is proposed to be controlled by a ‘default’ mechanism, for which the molecular regulation is not well understood. In this study, we investigated the functional roles Cited by:

New York, NY, USA – Some of the most deadly skin cancers may start in stem cells that lend color to hair and originate in hair follicles rather than in skin layers, a new study follicles are complex organs that reside within skin layers.
It is there that immature pigment-making cells develop cancer-causing genetic changes and. Embryonic stem cells are totipotent cells as they can differentiate to any type of cell in the body. Ability to differentiate into cardiomyocytes, endothelial, and smooth muscle cells helps in repair of the damaged myocardium.
In animal models, the cardiomyocytes derived from the embryonic stem cells help improve myocardial function . In a. Embryonic Stem Cells and Gene Manipulation in Rat Chapter in Methods in molecular biology (Clifton, N.J.) June with 15 Reads How we measure 'reads'.
While this technology is routinely used in mouse ES cells, it has recently been successfully developed in human ES cells (See chapter 4: Genetically Modified Stem Cells), thus opening new doors for using ES cells as vehicles for gene therapy and for creating in vitro models of human genetic disorders such as Lesch-Nyhan disease.

Scientists discovered ways to derive embryonic stem cells from early mouse embryos nearly 30 years ago, in The detailed study of the biology of mouse stem cells led to the File Size: KB. The rat’s name was Fighter, and she had been given a derivative of embryonic stem cells, which restored function to her limbs.
(This was the famous stem cell therapy begun by Hans Keirstead with a Roman Reed grant, developed by Geron, and later by CIRM and Asterias, which later benefited humans.).
Embryonic stem cells are grown from cells found in the embryo when it is just a few days old. In humans, mice and other mammals, the embryo is a ball of approximately cells at this stage. It is known as a blastocyst and has two parts: An outer layer of cells, or trophectoderm, will form the placenta that supports the embryo as it grows.

The first forays into understanding pluripotency in the mammalian embryo began with rather simple experiments in which pieces of mouse germ cell tumors known as teratocarcinomas were grown in culture and a variety of pluripotent cell types emerged (Solder, ).One cell type, termed Embryonal Carcinoma Cells (ECCs), produced Cited by: 3.
Framing the Issue Stem cells are undifferentiated cells that have the capacity to renew themselves and to specialize into various cell types, such as blood, muscle, and nerve cells. Embryonic stem cells, derived from five-day-old embryos, eventually give rise to all the different cells and organ systems of the embryo.
